5. Effects of virus on organism

Citrus psorosis virus

• Bark Scaling (bulging and breaking) and Internal Staining
  • Trunk and Limbs
• Form A
  • More passive
  • Restricted to main trunk
  • May show some spots in younger leaves
  • Older leaves relatively unaffected
  • Takes place at 10 - 15 years of age

• Form B
  • Aggressive form
  • Same symptoms but also extensive bark scaling and chlorotic blotches
  • It can also cause leaf drop and shoot necrosis (premature death of living tissue)

Tulip Breaking Virus

• Only one main symptom
  • Weakens the tulip plant
  • Allows the leaves to display a wide variety of colors
  • Makes them highly desired because of the mix of colors the virus causes

Tobacco Mosaic Virus

• Veinbending
• Necrotic symptoms
  • Mosaic burn
• Small bulging in the leaves
• Hard to detect visually for most cases
